Abstract

This document is the second edition of version 1.1 of XHTML Modularization, an abstract modularization of XHTML and implementations of the abstraction using XML Document Type Definitions (DTDs)
and XML Schemas. This modularization provides a means for subsetting and extending XHTML, a feature needed for extending XHTML's reach onto emerging platforms. This specification is intended for use
by language designers as they construct new XHTML Family Markup Languages. This specification does not define the semantics of elements and attributes, only how those elements and attributes are
assembled into modules, and from those modules into markup languages. This update includes several minor updates to provide clarifications and address errors found in version 1.1.

Status of This Document

This document is a W3C Proposed Edited Recommendation. If approved, it will supersede the previous edition of XHTML
Modularization 1.1. It reflects minor corrections to ensure consistency among various markup languages that rely upon XHTML Modularization. Most significant among these are:

Changing the datatype of the class attribute so that it permits an empty value - historically the class attribute was permitted to be empty.

Moving the name attribute for the form and img elements out of the legacy module and into their base modules - this attribute is required for some scripting
constructs.

Changing the datatype for the usemap attribute from IDREF to URIREF - most user agents require that map references be relative URIs that are local to the
document.

Publication as a Proposed Edited Recommendation does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time.
It is inappropriate to cite this document as other than work in progress.

W3C Advisory Committee Members are invited to send formal review comments on this Proposed Edited Recommendation to the W3C Team until @@@@SOME DATE@@@@. Members of the W3C Advisory Committee will
find the appropriate review form for this document by consulting their list of current WBS questionnaires.
